<p>A method and apparatus for admixing liquid with a shear-thinnable concentrate (11) of photographic processing composition to form a photographic processing solution, in which the concentrate is thinned by shear forces and contacted with the diluting liquid under turbulent mixing conditions to dissolve the concentrate in the liquid and thereby form the solutions. The concentrate, which does not flow and resists deformation under conditions of low shear, is displaced from a tube-like container (13) through an orifice (37) where conditions of high shear render it free-flowing and form a stream. One or more liquid jets (51, 53, 55) are directed at the stream with sufficient force to disperse the concentrate under turbulent mixing conditions. A mixer (57) then completes the dissolution of the concentrate in the liquid. </p> |
